Another species am particulary fond of is this miniature microsorum that is known in Thailand. It approximately grows upto 4inches in height. Grows as an epiphyte or with peat moss or fern chips.
Here are some of the Philippine species of microsorum am very proud & fond of - most of these have been found & collected by local gardeners in the late 90's and early 2000 - unfortunately it is not commonly found in big production quantity.
